Havermann recommends selecting material visually. ?Don?t feel tied to categories (annual, tropical, perennial). Look at colours, textures and growth habits, as well as plant needs. But let your instincts tell you what?s right,? she says. The pair?s palette includes shrubs such as barberry and boxwood, tropicals (caladium and canna are favourites), perennials such as stonecrop, coral bells and spurge, and a raft of annuals like plectranthus, New Zealand flax, oxalis and all kinds of herbs.
